Outline

1	Effects of Crystallographic Surface-Symmetry on the Resonant Charge Transfer of Ion-Surface Interactions
2	Resonant Charge Transfer Classically à Barrier Tunnelling Jellium Surface à 3-D Decay of Electrons Real Surface à Structured Decay
3	Band Gap and Ion-Fraction
4	Are structural distinctions of a gap innocuous ?
5	Effective 1-d Surface Potentials
6	Free Parallel Motion Dispersions
7	Propagation Methodology
8	Fixed-Ion (Adiabatic) Propagation
9	Quantum Beats from Reflections
10	Projected Density of States
11	Fixed-Ion (Adiabatic) Energies & Widths
12	Moving-Ion Propagation
13	Survival Probability for Slow Collisions
14	Weighing with Experiments
15	Bottom Lines Localizing reflections for Cu(111) band gap show confinements along surface normal For Cu(100), reflected electrons turn back into the metal through couplings with the bulk Image states are important for close distances but their evolution depends on the surface symmetry The ion survival is determined through the combined effects of the interaction time and distance of closest approach For non-grazing incidences, agreement with experiments is good
16	Outlook Propagation with real 3-d potential Applications to stepped surfaces Applications to metallic nanowires, quantum dot arrays etc.
